A CRYPTOGRAPHIC TECHNIQUE FOR ENCRYPTING PLAIN TEXT DATA INTO A COMPOSITE IMAGE CIPHER THAT IS CAPABLE OF BEING UNLOCKED IN PARTS USING MULTIPLE DECRYPTION PADS
A CRYPTOGRAPHIC TECHNIQUE FOR ENCRYPTING PLAIN TEXT DATA INTO A COMPOSITE IMAGE CIPHER THAT IS CAPABLE OF BEING UNLOCKED IN PARTS USING MULTIPLE DECRYPTION PADS
The invention is a process to encrypt and decrypt compound visual cryptographic images. During the encryption process multiple plain text messages are enclosed using multiple encryption pads and combined to form a complex cipher text. During each decryption process a portion of the cipher text can be decrypted to obtain one of the original plain text messages. This invention is planned to be used for unique identification of multiple users. The process also includes a method to create the optimum number of cipher texts required using an algorithm given a pre-determined number of decryption options.
